This adds a new function called by MSI handler in DesignWare PCIe framework, that invokes PME and AER funcions to detect the factor from SoC-dependent registers. The iATU patches is split from this series as "PCI: dwc: Move iATU register mapping to common framework". Changes since v7: - Add Reviewed-by: line to 1st and 3rd patches Changes since v6: - Separate patches for iATU and phy error from this series - Add Reviewed-by: line to dwc patch Changes since v5: - Add pcie_port_service_get_irq() function to pcie/portdrv - Call pcie_port_service_get_irq() to get vIRQ interrupt number for PME/AER - Rebase to the latest linux-next branch, and remove devm_platform_ioremap_resource_byname() replacement patch Changes since v4: - Add Acked-by: line to dwc patch Changes since v3: - Move msi_host_isr() call into dw_handle_msi_irq() - Move uniphier_pcie_misc_isr() call into the guard of chained_irq - Use a bool argument is_msi instead of pci_msi_enabled() - Consolidate handler calls for the same interrupt - Fix typos in commit messages Changes since v2: - Avoid printing phy error message in case of EPROBE_DEFER - Fix iATU register mapping method - dt-bindings: Add Acked-by: line - Fix typos in commit messages - Use devm_platform_ioremap_resource_byname() Changes since v1: - Add check if struct resource is NULL - Fix warning in the type of dev_err() argument Kunihiko Hayashi (3): PCI: portdrv: Add pcie_port_service_get_irq() function PCI: dwc: Add msi_host_isr() callback PCI: uniphier: Add misc interrupt handler to invoke PME and AER drivers/pci/controller/dwc/pcie-designware-host.c | 3 + drivers/pci/controller/dwc/pcie-designware.h | 1 + drivers/pci/controller/dwc/pcie-uniphier.c | 77 +++++++++++++++++++---- drivers/pci/pcie/portdrv.h | 1 + drivers/pci/pcie/portdrv_core.c | 16 +++++ 5 files changed, 87 insertions(+), 11 deletions(-)
